application fled September 8, 1821, Serial No: 438;,708. Renewed August28, 1987 I Th1s 1I1V6Ill310l1 relates to that type of ironing machinesin which the dampened clo es are drawn over .a smooth heated surface bymeans of a padded roller, and the object of this invention is to producea mangle of this character in which the stationary surface shall besubstantially horizontal and be heated in the most economical manner,.in

which the padded roller may be caused to move substantially verticallyaway, from the heated surface by mechanism connected to the operatingmotor upon the application of minimum ressure to a control lever, and inwhich file outer surface of the padded roller is so freel riod of timethat any moisture" absorbed y the paddin thereon while in contact withthe work as ample time to eva orate before again coming 'in' contact wit.wet

clothes. I

This invention consists of a hor zontal padded roller andmeans'to rotateit, of a smooth shoe mounted below the roller and means to heat theshoe, the upper surface of theshoe being cylindrical and substantiallyconforming to the roller, of mechanical means to elevate the'roller, andof a control device actuated by the operator for caus' the means forrotating the roller to drive t e means for elevating it. I

It further consists of. manually operable means for elevating the rollerindependent of the mechanical means therefor.

-. It also consists of mechainical means-for returning the roller intocontact with the shoe upon the succeeding; actuation of the controldevice by the operator.

It also consists in the details of constructionillustrated in theaccompanying drawaperspective 'viewof ings and claims. y In theaccompanying drawings, Fig. 1 is t is improvedmangle.

Fig. 1 is a detail showing the spring to return a pedal. Fig. 2 is adetail of the gears to drive the padded roller. Fig. 3 is an elevationof the left endof the mangle,

the cap over the end of the frame being removed. Fig. 4 is acentralvertical trans verse section of the'roller, shoe and burner, seenfrom the right. Y Fig. 5 is an elevation from the right of the mangle,parts thereof being broken away to show. the details: Fig. 6 is a Ionitudinal section of the left end of the mang e. Fi 7 is [asimilar'section of l the right end 0 the machine. 'Fig. 8 is a exposedfor a maximumparticularly pointed out in' the Similar reference'characters refer to like parts throughout the several views.

The present mangle is provided with legs 1, preferably bent from roperlyrolled bars, connected by the cross ars 2 as shown in Fig. 1'. Pivoted-to the front legs is a treadle 3 to which the lower' end'of the controlrod 4 is connected. Cross rods.5 may be used to stiffen this structureCarried by the central transverse tops 6 of the legs are the end frames7 and 8 betvgeen which the stationary shoe 9, shown in cross section inFig. 4, extends, its end flanges lO being secured to the frames by thebolts' 11.

he upper surface 13 of this shoe conforms,

substantially through the greater art of its width to the pad 14 on therollerl lmwhich is secured on the shaft 16 and is rotated therebyi'nthedirection indicated 'by the arrow in Fig. 4. The front edge 17 of theshoe is cut away to form a cylindrical-surface to freely admit thearticles to be ironed, and a feed board 18, having end flanges 19,

is secured to the end frames, as indicated in proper introduction ofFig. 4, to facilitate the clothes. I

.- The burner pipe 21 extendsbeneath the.

shoe and has jet openings 22 'which cause the flame to pass along thebottom of the shoe,

pins 23 extending down from the shoe into the flame to render the flamemore=elfec- Qtive. A'shell 24 extends beneath the shoe and burner tubeand its openings 25 and 26 cause the flame to move transversely ofthe-shoe. Any desired; valve mechanism 27 (Fig. 6) may be'employed, Thelip 28 on thiscasingprevents the article being ironedfrom closing theseopenings 26 butdoesnot prevent the hot gases from'passing through mayremain therein. 6 v

The roller shaft 16 is mounted in bearings 30 and 31.which are slidablein slots 32 and 33 in the, frames. These bearings are movable'up anddown inthe slots by means'of the eccentric 34 at the right end of themachine and the crank 35 and crank pin 36 at part roller-control shaft3738 whose operthe', clothes to finally dry out the steam which theleftend, both being mounted on the twoation will be described fartheron. This shaft 37-38 is in two parts for convenience of manufacture andassemble and rotates one half turn at each actuation of the controlmechanism therefor The connecting rod between the crank pin 36 and thebearing 31 for the left end of the shaft 16 is largely a spring, 40which is screwed onto a spirally grooved hub 41 on the bearing 31 and ona spirally grooved hub 42 of the eye 43 into which the pin 36 extends.These two hubs are kept in alinement by a rod 44 slidable therein. Thisspring and its mate at the other end of the maclnne determine thepressure of the roller 15 against the shoe and while normally tight,these springs expand to permit the roller to yield sufliciently to allowclothes to ass through the machine. Should any clot es become bunched, atouch on the control device causes a half-rotation of the control shaftand an elevation of the roller, while a second half-rotation -of thisshaft returns the roller to operative position. The eccentric yoke 46 onthe eccentric 34 has a spirally grooved hub 47 which receives the spring40 at that end of the machine and the action is similar to that justdescribed.

The frame 7 has a. bracket 49 ouwhich the electric motor 50 may bemounted, and its shaft 52 is mounted in the bearing 53 carried by theremovable front plate 54 of this frame. On this shaft is a worm 55 whichmeshes withthe worm gear 56 attached to the sleeve 57 which is loose onthe part 37 of the control shaft. I have shown (in Fig. 7) this wormgear screwed onto the outer end of the sleeve, a toothed clutch disk 58screwed onto the inner end of the sleeve, and a sprocket wheel 59 formedon the sleeve intermediate its ends, but these parts may all be integralif desired.

A pin 61 is mounted in the upper end of the frame 7, as indicated inFigs. 5 and 7, and the yoke 62 thereon carries a drive shaft 63 at itslower end, to which the sprocket wheel 64 and pinion 65 are connected. Achain 66 connects the sprocket wheels 59 and 64 and the pinion mesheswith the gear 67 on the end of the roller shaft 16. The grooves 32 and33 in which the bearings 30 and 31 are slidable are curved around theaxis of the shaft 63 as a center when that is in a position shown inFig. 5, when the pinion 65 meshes with the gear 67. This permits theroller shaft to he moved up and down without disengaging the drivinggears therefor. The are through which the shaft 63 swings has no effect'on the engagement of the sprocket chain and its wheels.

Mounted in the frame 7 is another shaft 69 on whose outer end is ahandle 70 by which this shaft may be turned. On the inner end ofthisshaft is a cam 72 which 1 engages the yoke 62 and normally holds it inthe position shown in Fig. 2, but when the handle is swung to the leftin Fig 2, to free this yoke 62, the weight of the yoke and the pressurebetween the driving gears causes disengagment of the gears so that thishandle controls the rotation of the roller.

The mechanism which connects and disconnects the control shaft 3637 toand from the motor and notched clutch disk 58 is as follows. Mountedwithin the frame. 7 on the shaft 37 is a. clutch frame 74 in which aclutch head 75 is rotatable in the direction of the arrow thereon inFig. 5. Endwise movement of this clutch head 75 is prevented by theclutch disk 58 and by the eccentric 34, while endwise movement of theclutch frame is prevented by the clutch head 75 and the eccentric 34.Rotation of the clutch frame is revented b a lug 78 on the bracket 79which lug exten s into a notch 80 in the clutch frame 74. The clutchhead is provided with guides 76 between which are the T sha edroovesinwhich the clutch keys 77 are slldab e. I prefer to form the rearwalls of these slots radial and while the inner ends of the clutch keysare of the same thickness as the .clutch disk 58, the

shoulders 75 thereon project above the plane of the clutch head andframe. See Fig. 10.

The clutch keys 77 are normally in the position shown in Fig. 5.Whenever the treadle 3 is depressed, the control rod 4 pulls down thecontrol lever 82 (Fig. 5), which is pivoted at 183 on the bracket 79which is attached to the frame 7. This action causes the arm 188 on thislever to compress the spring 85 and to force the pin 86 inwardly. A pin87 on the clutch frame supports the latch 83 which has an arm 84 in thepath of the pin 86 and a hook 88 adapted to engage the end of the latchfinger 89 which is pivoted on the pin 90 carried by the clutch frame. Aspring 91 extends up from a. lug 92 on this latch finger 'to the pin 93on the latch 83 to normally hold down this latch, while a second spring94 extends from this lug 92 to a pin 95 on the clutch frame. Cams 96 areformed on the clutch head to return the latch finger to normal position.

\Vhenever the roll 15 is to be raised, the threadle 3 and the controllever 82 are depressed, the pin 86 is forced inwardly against thetension of the spring 85, the latch 83 is swung on its pivot against theforce of the spring 91 and the upper end of the latch fin er 89 isreleased from the hook 88. The atch finger is now swung toward the shaft37 by the spring 94 and as the latch finger bears against the adjacentclutch key 77 this key will be moved into the next notch 97 in theclutch disk 58 and this results in the clutch head 75 being carriedaround by the clutch disk. As

shown in Fig. 7, the clutch head and the eccentric 34 are secured to theouter part 37 of the control shaft by the key 98 so that In order torelease the control shaft from the motor, the following describedmechanism is employed. See Figs. 5, 9 and 10. Extendin over the clutchhead is a plate 99 secure to lugs 100 on the'clutch frame, which platecarries apin 101 on which the small cam arm 102 is mounted to swing inthe path of the shoulders v75 of the clutch keys 77. A lip 103 on thiscam arm extends up above the plate and receives one end of the spring104 which connects to the outer end of the cam arm 102,. while a h 105on the plate extends down into the pat of this cam arm.

Whena clutch key 77 reaches the cam arm 102, its. inner end is in anotch 97 in the cam disk 58" and its shoulder 74 slides along theoutersurface of the cam arm 102 and swings that "arm inwardly. until the,pull of the spring 104 is sufliciently reat to overcome t e friction ofthe key 7 in its notch or until the arm 102 en ages the lip 105 on theplate 99, when further rotation forces out the clutch. key. In eithercase, the spring 7 and 8, the inner ends of the levers being beneath thebearings 30 and 31 and the outer ends connecting to the rods. 114 which.extend down tothe yoke 115 pivoted to the cross bars 2,- as shown inFig. 1. One arm 116 of this yoke extends forward so that the operatormay step onto its forward end and thus force up the roller against thepull-of the springs sufliciently to release goods between the roller andshoe. In order to.

hold the roller 15 elevated, the arm 116 may be formed with a notch 120which may receive the edge of the adjacent leg 1 when this upm isdepressed and swing sid'ewise to permit such enga ement. This may beimportant to save tl As soon as the motor starts running again it liftsthe roller so much higher than does the arm 116 that theload is removedthere'- from which permits the spring 121-to swing the yoke 115 tonormal osition. This yoke is preferably formed 0 a central tube with 1epadding on the roller.-

its ends. bent forward and this tube is mounted on a rod 122 extendingbetween the side bars 2 as shown in Fig. 1.

As the operator stands before the machine, both hands are .free 'tospread the work so they will pass between the shoe and roller, thework-falling. onto the table 110 and therefore being convenient to theoperator should a' second passage be desirable.

The roller is" entirely free from-the work 104 swings out the cam arm102 immediately for about three fourths of its circumference,

after the key 'is released and holds this key from accidental engagementin a notch in the clutch disk. After the clutch head has turned untilthe key no'longer engages the a vertical plane is'suflicient to with ahole 118 and the late .finger 119 extending into this hole.

cam arm 102, the inclination of the key ,on

4 prevent inward movement thereof.

When the clutch head has turned about Two stop lugs 108 and109 areprovided on the clutch frame 74 to prevent rotation of the clutch head,the former preventing forward rotation and the latter rearward rotationof the clutch head when the clutch keys are; in their outward positionsshown in Fig. 5. A table 110 may be attached to the-tops of the legs ifdesired.

To prevent clothes being burned should the motor stop while suchclothesare between the roller and shoe, a pair of levers 112 are mounted onpins 1131-on the frames which permits the moisture in the padding toevaporate freely, there being no shield or obstacle to prevent. suchevaporation. .Should the goods become bunched,-'slight pressure on thetreadle 3 instantly causes the roller to rise to free the work andpermit the goods to be straightened out. With eight teeth in the clutchdisk 58, the pinion 65' one eighth the diameter of the gear :07, andthe'sprocket wheels at the ratio of 7 to 10, the roller 15 may turnthrough from thirty to forty degrees from the time/the pedal '2 isdepresseduntil the roller reaches. its maximum. elevation, orin time, asmall fraction of a second.

The details and proportions of the various parts may all bechanged bythose skilled of our invention as ing claims.
